Look at this. A bright spot of light is sitting on the wall, but the torch is pointing somewhere else. How did the light get there?
Today we will find out three things light can do: bounce, split into colours, and help us see tiny things more clearly.
Which are you most curious about right now: bouncing light, or light that splits into colours? Tell your partner why.
Two quick pictures for today:
A torch beam can hit a shiny mirror and the bright spot can land somewhere new.
Ordinary white light can open out into rainbow colours when something spreads it.
Later we will also look at tiny print through a curved glass and notice what changes.
Three stations are ready. Try the challenge at each one and notice what the light does.
Station A — Bounce: shine the torch at the mirror. Can you land the bright spot on the target card?
Station B — Split: send light through the clear triangle block (the prism). What colours appear on the white card?
Station C — Closer look: read the tiny-print card with bare eyes, then through the magnifier. What changes?
Before you leave each station, sketch or jot one thing the light did on your Investigation Journal page.
Stay at each station until I call the rotate. Keep torches away from eyes and faces.
Stations are finished. This bounce round is a real investigation, not free explore.
In threes at a Bounce table: one holds the torch still, one tilts the mirror, one is the spotter. I will place your target.
Before you move anything: predict where the bright spot will go if you tilt the top of the mirror toward you.
Then test: shine only at the mirror, keep the torch still, and tilt until the spot lands on the target. When you hit it, move the target once and bounce again. Be ready to say what you changed.
Open your Investigation Journal page. Tidy the quick notes you started at the stations and add the bounce investigation.
Check you have something for each part:
Write or draw what you saw.
